Guostaus ežeras, Guostus, Guostus Lake area
Guostus Lake is a large waterbody in Stakliškės Eldership
Guostus Lake lies in Prienai District Municipality, about 3.5 kilometres northeast of Stakliškės. The local municipal page says the lake is visited by holidaymakers and gives its area as 74 hectares.
The nominative name in official nature references is Guostus, while local directions often use the genitive form Guostaus ežeras. These are two forms for the same lake, not two separate places.
The map point on this page is approximately 54.607509, 24.374397. It marks a representative waterside location, so it should not be read as the exact start of the entire shoreline or as the address of a guaranteed public beach.
High shores, forests, and a gravelly lake margin
The Universal Lithuanian Encyclopedia describes Guostus as a glacially formed lake in a channel basin. It is about 2 kilometres long, up to 0.6 kilometres wide, and its surface stands at 151.9 metres above sea level.
The shores are high and steep, so the view can be striking while access is not equally easy everywhere. The Būdai and Lielionys forests approach from the southwest and give the lake a strong green backdrop.
The littoral is described as narrow and gravelly, with little aquatic vegetation. The VLE records a maximum depth of 33.7 metres, so a calm surface does not reveal the underwater relief or establish that swimming is safe.
Waterside recreation depends on the chosen access point
Guostus Lake works for a slow waterside outing, landscape watching, and a short stop between other sights around Stakliškės. A large lake does not have one uniformly developed shore, so plan a particular access point instead of treating the entire shoreline as a public recreation area.
The Stakliškės Eldership page mentions Z. Klizienė’s rural tourism homestead by the lake. That is a private accommodation and leisure business, so its services, access conditions, and opening hours should not be assigned to the whole lakeshore.
High shores and gravel can become slippery after rain. Supervise children closely near the water, do not enter private land without permission, and swim only where the particular place allows it and conditions are suitable.
Guostus is included in the Stakliškės route
The Prienai District Municipality route page describes a 21-kilometre Stakliškės route. Its sequence includes the Stakliškės Holy Trinity Church, the Gojus Forest Oak, a partisan dugout in Gojus Forest, Lepelionys Hillfort, Guostus Lake, and the malt tower museum of the Stakliškės brewery.
This route lets you plan Guostus Lake as one of several meaningful stops rather than the only goal of the day. Spend time by the water, then continue to a hillfort, old oak, or cultural site in the Stakliškės area.
The route length does not indicate how long your waterside stop will take. Leave extra time for a quiet visit because different approaches can have different road surfaces and distances from the water.
How to plan a quiet Guostus Lake visit
Allow one to three hours for a chosen shore point, a short walk, and unhurried time outdoors. Combining the lake with the full Stakliškės route requires considerably longer.
Before travelling, check whether the chosen approach suits your vehicle, and follow road and private-property signs on site. One map point does not confirm that a car park, toilet, changing booth, or lifeguard will be beside the water.
A dry, warm day from late spring through early autumn is easiest for landscape viewing and waterside rest. Bring non-slip footwear, drinking water, a bag for your waste, and leave the sensitive shore without a trace.
